A continuación, se presentan ejercicios resueltos paso a paso, variando la incógnita a despejar. Ejercicio 1: Cálculo del Área Final de una Placa dilatacion superficial ejercicios resueltos

: A PDF problem set covering various types of thermal expansion, including cross-sectional changes in steel. Solved Example Step-by-Step Problem: A glass window has an initial area ( A0cap A sub 0 21∘C21 raised to the composed with power C . What is its final area ( Afcap A sub f ) if the temperature rises to 35∘C35 raised to the composed with power C Identify the variables: (coefficient of superficial expansion) for glass (value varies by glass type). Apply the formula:

Luego, podemos calcular el cambio en el volumen (ΔV): ΔA=A0⋅β⋅ΔTcap delta cap A equals cap A sub

$$A_f = A_0 (1 + \beta \Delta T)$$ $$A_f = 25\pi \left[1 + (24 \times 10^-6)(200)\right]$$ $$A_f = 25\pi \left[1 + 0.0048\right]$$ $$A_f = 25\pi \left[1.0048\right]$$ $$A_f \approx 25.12\pi , \textcm^2$$
